Electredge Posted July 13, 2020 Report Share Posted July 13, 2020 I am more familiar with using End of Injection, when I try to use that on a G4x it tells me if I plan to use a Fuel Cut in Seq. mode I should use Start of Injection. Just wanted to understand why that is. Thanks bradsm87 1 Quote Link to comment Share on other sites More sharing options...
Vaughan Posted July 13, 2020 Report Share Posted July 13, 2020 when using a fuel cut with staged injection the fuel cut has to cut both injectors completely for that cycle otherwise it will run lean instead of just not igniting. The need to use Start of Injection with a staged setup comes from needing to be absolutely sure that neither injector has started putting fuel in before deciding to cut for that cycle (if using end of injection the angle that the injection starts at is dependent on a lot of different variables which are constantly changing).
